For centuries now people around the world have been fascinated by ancient Egyptian culture and the colossal pyramids that they created to honour their pharaohs. One way to visualise the fascinating pyramids and to come to an understanding of the pyramid shape is to construct a 3D pyramid from marshmallows and toothpicks.
Lay one piece of construction paper on a flat surface and spread a thin layer of tacky or craft glue all over the construction paper.
Place 25 marshmallows on the glue-covered construction paper in five rows of five marshmallows. The five rows should be placed side by side with the rows touching one another.
Layer 16 marshmallows, four rows of four marshmallows each, on top of the previously glued bottom layer. The second layer of marshmallows should be centred above the bottom layer.
Anchor the two layers of marshmallows by pushing toothpicks that have been cut in half through the top of the second row and into the bottom row of marshmallows. Place one toothpick per marshmallow in the second row to anchor the construction securely.
Place the third level of marshmallows, three rows with three marshmallows in each row, on top of the second layer and anchor the third layer with the toothpicks. The third layer of marshmallows should also be centred prior to anchoring.
Place the fourth level of marshmallows, two rows of two marshmallows each, centred directly above the third layer and anchor with the toothpicks.
Place one marshmallow directly at the centre of the construction on top of the fourth level and anchor with a toothpick.
Cut the toothpicks in half prior to starting the construction process. If desired, whole toothpicks may be used for the third, fourth and fifth layers of the construction for additional support.
